A system where a subgroup of nodes in the network keep track of what's being broadcast and a bunch of math that makes sure people are being kept from getting gaslighted with false information by a swarm of malicious nodes.
It can be used for bank-like records.

Bitcoin was the first one designed in a way that everybody could join while also being save as long as more than 50 of all nodes aren't malicious.
It achieves this by an overhead of a shitload of "wasted" electrical energy.

A more naive approach to keeping such a communal record is instead to broadcast more and not only ask people for their data, but also to forward what other people have said to them, to find out if somebody is telling different people different storties. That has a lower % of savety, but is more straightforward to understand:
